    By combining the thermal-induced spectral broadening of Er3+/Yb3+ co-doped crystal and the high ratio of cavity gain to loss, a high-power broadband continuously tunable 1.5-1.6 μm laser was successfully demonstrated in an Er:Yb:YAl3(BO3)4 crystal. End-pumped by a continuous-wave 975.6 nm laser diode, three discrete tunable laser bands in 1483-1488, 1495-1503, and 1521-1612 nm were realized at an incident pump power of 7.7 W. The maximum continuously tunable bandwidth was up to 91 nm in 1521-1612 nm, and the maximum output power was 474 mW at 1551 nm. The output power was generally higher than 100 mW in the whole tunable range.
